IMPROVED CALENDEBING-MACHINE.

*HOM- The Schedule referred to in' these Lettera Patent'and making-.part of the same.

To all whom it may concern Be it known that I, HENRY F. ROGERS, of South -Manchester, county of Hartford, and State of Connecticut, have invented certain new and useful Improvements in Paper-Oalendering Machines; and to enable others skilled in the alt to make and use the same, I will proceed to describe its construction and Operation, referring to the drawings, in which. the same letters indicate like parts in each of the figures.

The nature of this invention consists in arranging Y calender-rolls upon the outer ends of arms, or upon the surface of a cylinder formed on said arms, thel whole being secured and rotating upon a shaft having its bearings in boxes. VThe calender-rolls, thus 4arranged, are caused to rotate over a b ed, arranged in a cylindrical circle, and the material being Afed into or between the bed and the rolls, revolving over its surface by means of a pair concave and convex rollers, placed closely to the side ot' the workingsurface ofthebed. Said rollers serve both to feed 'and to give shape to the material, corresponding-to the shape or curve of the hed as it is being introduced upo'n the bed, to the action of the calender-rolls.

In the accompanying drawings- Figure l is a side elevation.

Figure 2 is a top View. a is the frame-work of the machine, to which all the mechanism is secured.

b is a segmental or cylindrical forma tion, upon which is secured a bed-plate, b.

The object of this plate b' ist-o form a bed for the l paper, or other material to lay upon, while the calen-v der-rolls successively work upon its surface, and move forward, (the paper,) alternately, after the action of the rollers thereon.

(I are arms or cylinders, upon which the calender- 'rolls aresecured.

These arms or cylinders are secured on the shaftd', and have their bearings in boxes, c.

These boxes are secured, iu an adjustable manuel',

to posts or frame-work a, by means of fastening-Screws or bolts j'. lhese boxes are also provided with slitopenings, through which the 'tsteuiug-bolts f pass,

yboth for the purpose of 'holding theboxes, and for adjusting or regulating the position and action of the calender-rolls upon the plate b', and by which the said: rollers may be made to act in an angular direction vupon the-material layingupon thephed-plate.

g are boxes, Secured to the arms ,or vcylinder by screws, gl, and when desirable, an elastic or India-rubber pad, g2, is placed between the box and cylinder t0 relieve concussion.

These boxes are also provided with elongated openings for the roller-bearings, and in which the bearingsof the rollers are adjusted, by means of set-screws,-

g, or their equivalents.

t are calender'rolls, their bearings heilig .arranged in the boxes g. The face of these rolls Should be made slightly rounding, so as to 'allow of their being arranged to act upon the bed, or material thereon, in a slightly angularmanner, in relation tothe bed-plate.

hflare feed-rolls, which have their bearings in the stu'ds h', Vand are operated. bya pulley, 1'. These rolls are made, one concaveaud the other convex shape, more or less, so as to 4correspond with shape of, and in position with the bed-plate b.

lhe motion is imparted tovthese rolls through the pulley, or other suitable de-vice, whereby au alternate Vaction 0r movement s'prodnced, succeeding the action ofthe calender-roll mechanism in common use.

The-po wer is applied to operate the machine through' a pulley or crank, 7.'.

N ow, it will be seen,.that by the use of this invention, a continuous rotary motion of the calender-rolls x, may be produced, in connection .with an alternate act-ionor movement of the feed-rolls h, (produced by any of the well-known mechanisms) and thus produce the calender-ing effectupon the. paper, or other mate.

rial, more rapidlyand perfectly, and thereby avoiding the shake or jar of the building usually produced by the reciprocating machines now in use.

I believe I have thus shown the nat-ure, construction, and advantage ot' this invention, so as to enable others skilled in the art to make and useI the same therefrom.

What I claim, therefore, and 'desire' to secure hy`
